How it's done

How We Perform MacBook Thermal Paste Replacement

What our technicians do, what it requires, and how to tell you need it.

1 How It's Performed

When a component genuinely needs swapping rather than repairing, we fully disassemble the cooling path, clean out accumulated dust from the fan blades and heatsink fins (the single biggest real cause of creeping temperatures), remove the old dried-out thermal paste completely from both the CPU/GPU die and the heatsink contact plate, and apply fresh paste before reassembly.

Dried-out factory thermal paste is one of the most common causes of creeping temperatures on a laptop that is otherwise healthy — we always clean off the old compound fully before applying fresh paste, rather than layering over it.

Typical time: 30–45 minutes

2 What This Requires

  • Inspection of the fan bearing itself for wear (a grinding or whining fan sometimes needs replacing outright rather than just cleaning).

3 When You Need This

  • The laptop runs noticeably hotter or the fan is louder than it used to be under the same workload.
  • Performance drops under sustained use (thermal throttling) even though it's fine for the first few minutes.
  • Unexpected shutdowns specifically during demanding tasks (gaming, video export, large downloads).

Who repairs your device

Repaired in-house by Xigox technicians

MacBook Thermal Paste Replacement is handled by Xigox technicians from start to finish, never handed on to another shop. Work that needs the repair bench is done at our workshop in Virar West.

Board-level faults are traced with a microscope, a multimeter and a soldering station before any part is replaced, and parts are fitted only after you approve the quote.

We don't open your personal files during a repair. When a job needs access to your data, such as data recovery or a Windows reinstall, we ask you first.

  • Repaired in-house, not outsourced
  • Quote approved by you before work starts
  • Your files stay private
  • Microscope and board-level tools
  • Genuine or OEM-grade parts

MacBook specifics

What MacBook Thermal Paste Replacement Means on a MacBook

MacBooks are sealed, glued and board-integrated, so almost nothing is a plug-in swap. Repairs are component-level work on the logic board, not module replacement.

Why it happens on MacBook Air and MacBook Pro owners

  • Thermal paste degradation on tightly packed M-series and Intel boards
  • Blocked rear-vent airflow under the hinge
  • Liquid ingress through the keyboard into the logic board
  • Swollen battery pressing on the trackpad and top case

What our MacBook technician checks

  • Apple Diagnostics and full board voltage-rail read
  • Thermal imaging of the heat pipe and fan assembly
  • Corrosion inspection under the keyboard membrane
  • Battery cycle count and health via system report

MacBook hardware we work on

  • Apple Silicon M-series and Intel logic boards
  • Butterfly and Magic Keyboard assemblies
  • Retina display assemblies with bonded glass
  • Battery packs adhesived into the top case
  • Thunderbolt / USB-C charging boards
  • T2 security chip and SSD soldered to board

Models we see most often

  • MacBook Air M1 / M2
  • MacBook Pro 13" Touch Bar
  • MacBook Pro 14" and 16" M-series
  • MacBook Pro Retina 15"

Because storage is soldered on T2 and Apple Silicon boards, we take a full image before any board work so nothing is lost if the SSD controller is affected.

Do you use genuine Apple parts?

We use OEM-grade and original-pull Apple components, and we tell you which one your quote covers before any work starts. Board-level repair keeps costs well below Apple's whole-unit replacement price.
